Text field

Create the text field component. Make sure that it can expand to fit more lines, and use scrollbar if the message is too long. Make sure it can return the text that the user entered so that it can be included into the chat field.

Start by locating the existing chat field or frontend entry point where a text field component belongs, then inspect how entered text is passed into the chat. Confirm the component expands across multiple lines, uses a scrollbar for longer messages, and exposes the entered text for inclusion in the chat field.
